Draw a line in forward direction of a object

Question

I am trying to draw a line between the translate.forward direction and a point 20 unit further then the translate.forward point. This is the code I use (I added the LineRenderer component to the object):

 LineRenderer lineRenderer = mHead.GetComponent<LineRenderer>();
 lineRenderer.SetPosition(0, transform.position);
 lineRenderer.SetPosition(1, transform.forward * 10);

This is not working correctly (I think). Since when I use the Debug.DrawRay(...) it gives me another line code:

 Debug.DrawRay(transform.position, transform.forward * 10, Color.red, 0);

Does anyone knows how to do this correctly?

@sys12 suggested to change the code to:

  LineRenderer lineRenderer = mHead.GetComponent<LineRenderer>();
  lineRenderer.SetVertexCount(2);
  lineRenderer.SetPosition(0, transform.position);
  lineRenderer.SetPosition(1, transform.forward * 20 + transform.position);

This worked perfectly! Thanky You @sys12!
